This results in a larger light-travel time, larger distance and fainter supernovae, which corresponds to the actual observations. Adam Riess et al. found that "the distances of the high-redshift SNe Ia were, on average, 10% to 15% further than expected in a low mass density Ω M = 0.2 universe without a cosmological constant".

The true acceleration at time t is found in the limit as time interval Δt → 0 of Δv/Δt. An object's average acceleration over a period of time is its change in velocity, , divided by the duration of the period, .
This time happens to correspond roughly to the time of the formation of the Solar System and the evolutionary history of life. Stelliferous Era: 150 Ma ~ 100 Ta [19] 20 ~ −0.99: 60 K ~ 0.03 K: The time between the first formation of Population III stars until the cessation of star formation, leaving all stars in the form of degenerate ...
Map & traveler views of 1g proper-acceleration from rest for one year. Traveler spacetime for a constant-acceleration roundtrip. In relativity theory, proper acceleration [1] is the physical acceleration (i.e., measurable acceleration as by an accelerometer) experienced by an object.
Since the result was the same, it was shown that acceleration has no impact on time dilation. [28] In addition, Roos et al. (1980) measured the decay of Sigma baryons, which were subject to a longitudinal acceleration between 0.5 and 5.0 × 10 15 g. Again, no deviation from ordinary time dilation was measured. [30]
The Hubble constant H 0 has units of inverse time; the Hubble time t H is simply defined as the inverse of the Hubble constant, [50] i.e. t H ≡ 1 H 0 = 1 67.8 ( k m / s ) / M p c = 4.55 × 10 17 s = 14.4 billion years . {\displaystyle t_{H}\equiv {\frac {1}{H_{0}}}={\frac {1}{67.8\mathrm {~(km/s)/Mpc} }}=4.55\times 10^{17}\mathrm {~s} =14.4 ...
FIGS earnings call for the period ending December 31, 2024.
This deflection may equivalently be described as a light-time effect due to motion of the Earth during the 8.3 minutes that it takes light to travel from the Sun to Earth. The relation with is : [0.000099365 rad / 2 π rad] x [365.25 d x 24 h/d x 60 min/h] = 8.3167 min ≈ 8 min 19 sec = 499 sec. This is possible since the transit time of ...
